Sea Spider Destroyer

This is the build I used to pass the Sea Spider boss with ease. Right Arm 44-414 JVLN ALPHA Left Arm PB-033M ASHMEAD Right Shoulder SONGBIRDS Left Shoulder SONGBIRDS Head VP-44S Core CC-2000 ORBITER Arms DF-AR-08 TIAN-QIANG Legs VP-424 Booster BST-G2/P04 FCS FCS-G2/P05 Generator DF-GN-06 MING-TANG For Expansion, I used Assault Armor for a quick consecutive stagger and melee, if the boss is in range after it recovers from the previous stagger. The SONGBIRDS grenade launchers are the single best option for inflicting ACS strain on the Sea Spider and Staggering it. Paired with the ASHMEAD Pile Bunker for dishing out some serious damage once staggered, this setup will tear through the Sea Spider's health. This build works well in both boss phases, using explosive weaponry to stagger the Spider and then going in with the melee weapon.
